The invention provides an auxiliary frame assembly, a cabin framework assembly and a vehicle, the auxiliary frame assembly comprises an auxiliary frame body and two collision beams, the two collision beams are connected to the two ends, in the width direction of the vehicle, of the auxiliary frame body respectively, the collision beams extend along a straight line, and the two ends, in the extending direction, of the collision beams are a connecting end and a collision end respectively; the connecting end is connected with the auxiliary frame body, the collision end is used for bearing force, and the distance between the two collision beams is gradually increased in the direction away from a cab of the vehicle. According to the auxiliary frame assembly provided by the embodiment of the invention, the collision beam can decompose a part of collision force into force in the width direction of the vehicle at the moment of collision, the vehicle is pushed to transversely move in the width direction in time and quickly, the collision time of the vehicle and a barrier is shortened, the crumple amount of a cabin is reduced, and the safety of the vehicle is improved. The integrity of the whole structure of the cab is effectively ensured, so that the safety of a user is effectively ensured, and the reliability of a vehicle is improved.

    本公开提供了一种副车架总成、机舱骨架总成和车辆,副车架总成包括副车架本体和两个碰撞梁,两个碰撞梁分别连接于副车架本体在车辆的宽度方向上的两端,碰撞梁沿直线延伸,碰撞梁延伸方向上的两端分别为连接端和碰撞端,连接端与副车架本体相连,碰撞端用于承力,在远离车辆的驾驶室的方向上,两个碰撞梁之间的间距逐渐增大。根据本公开实施例提供的副车架总成,碰撞梁可以在碰撞的瞬间将碰撞力的一部分分解为在车辆宽度方向上的力,及时且快速地推动车辆在宽度方向进行横移,减少车辆与壁障碰撞的时间,降低机舱室的溃缩量,有效地保证驾驶室整体结构的完整性,从而有效地保证用户的安全,提高车辆的可靠性。
